What Causes the BMW 7 Series New Car to Make Noise When Turning?
2 Answers
BMW 7 Series new car making noise when turning can be caused by friction between plastic parts, friction between the steering column and floor mats, or insufficient lubrication of the steering column leading to high friction. Friction between plastic parts: Especially in new cars, the steering wheel is composed of various plastic components. If the gaps between these parts are too small, friction will occur when turning the steering wheel. This usually resolves after a break-in period. If the noise persists, try reassembling the steering wheel. Friction between the steering column and floor mats: This is a common issue, mainly caused by oversized aftermarket floor mats (such as full-coverage mats) coming into direct contact with the steering column. Adjusting the position of the floor mats or replacing them can solve the problem. Insufficient lubrication of the steering column, leading to high friction: Poor-quality sliding rings on the steering column can cause noticeable friction noises, such as rustling or squeaking sounds. Applying some mechanical grease can help alleviate this issue.
I've recently researched some noise issues in high-end cars. The new BMW 7 Series makes strange noises when turning, which might be related to tires or suspension system. If new tires aren't properly broken in or have surface defects, they may produce screeching sounds during turns - it's necessary to check if tire pressure is normal. Additionally, suspension components like shock absorbers or bearings might not be fully lubricated or have minor looseness, causing noise when under turning pressure. I recall BMW occasionally misses these details during factory testing, so I recommend taking it to an authorized dealer for comprehensive inspection - they can diagnose quickly. Don't ignore such noises since the car is still under warranty; free repairs can prevent future safety hazards. Long-term speaking, regular suspension checks are key to maintaining driving comfort, especially for luxury cars. Early intervention can extend vehicle lifespan, otherwise subsequent repair costs could be substantial. Developing a habit of monthly self-inspections can save much trouble.
